37 Preface وَقالَ موسىٰ رَبّي أَعلَمُ بِمَن جاءَ بِالهُدىٰ مِن عِندِهِ وَمَن تَكونُ لَهُ عاقِبَةُ الدّارِ ۖ إِنَّهُ لا يُفلِحُ الظّالِمونَYusuf AliMoses said: “My Lord knows best who it is that comes with guidance from Him and whose end will be best in the Hereafter: certain it is that the wrongdoers will not prosper.”1Cf. 6:135. The only argument in such a case is an appeal to God and to the ultimate Future. Both of these appeals require Faith. But even if you do not rely on anything so high, you can see that Falsehood or evils crystallised in ancestral customs are not going to do any one any good.
